APPARATUS FOR BURNING HYDROCARBON OILS.

SPECIFICATION forming part of Letters Patent No. 441,467, dated November25, 1890.

Application filed December 6, 1889. $erla1 No. 332,786. (No model.)

To all whom it may concern.-

Be it known that I, STEPHEN 'lHos. J. BRAY, a British subject, and aresident of Moscow, Russia, have invented certain new and usefulImprovements in Apparatus for Burning Hydrocarbon Oils, of which thefollowing is a specification.

My invention has for its object certain improvement in apparatus forburning hydrocarbon oils, or what is commonly called liquid fuel.

In the accompanying drawings, Figure 1 is an elevation of my saidapparatus as ready for use. Fig. 2 is a longitudinal section of the sameon the line a b, Fig. 1, and Figs. 3, 4, 5, and 6 are end views andsections on lines o d and e f, respectively, of the instrument.

The tube 1) has a steam-inlet at c, and the inner surface of itsdischarge end is made cone-shaped. A pipe 10', screwing into thesteam-tube and having its discharge end cone-shaped both externally andinternally, is adjustable in the tube by means of the screw part pPassing through the pipe 19' is a pipe e, adjustable therein by means ofthe screw part at 2". The oil (from any suitable reservoir) enters bythe inlet a and passes through openings n, Figs. 2 and 5, in the pipe10, into the space N, between the pipes 10 and 6. By adjusting the endsof these different pipes with regard to each other any suitable amountof steam and oil may be permitted to pass out. The pipe 6 is an adjustable regulating-spindle, which admits the oil to be consumed to comein contact with the steam, and which is made tubular to admit a centralcurrent of air to relieve the Vacuum which would otherwise be formed,and to insure a regular flow of the oils to be burned.

The mode of operating the instrument is as follows: Steam is turned oninto the space I) and regulated to suit the requirements by means of theadj usting-cone p, which may be turned by hand or by a wrench at 10 andwhich 4 5 when once set requires no further adjustment. The oils to beburned are allowed to flow without hinderance into a space a, Fig. 2,and by unscrewing a hand-wheel O the oils will pass through space N andcoming in contact with the steam, will be completely atomized and drivenforward into the furnace. As seen by the drawings, the cone-shapedoutlet for the steam is more convergent than that for the oil. Thus theflow of steam is forced directly 5 5 into the stream or spray of oil.

I fit to the burner a cylindrical shield G, (shown in the drawings,)into which air is blown through holes Z andthe open outer end of thisshield has a few wires A at right angles to the axis of the shield.Against these wires the atomized oils are dashed, so that the gases orvapors composed of oils, steam, and air are intimately mixed, and fromthis point begins a broad, steady, and economical flame.

I wish it to be understood that I do not confine myself to the size ofany part shown in the drawings, nor to the kind of metal .or material itmay be made of; but

I claim as my invention- A burner consisting of an outer steam-tube witha conical discharge end, an adjustable oil-tube within the latter, and acentral regulating-spindle hollow to admit air, in combination with ashield fitted to the end of these 7 5 STEPHEN THOS. J. BRAY.
